: Macular edema (ME), due to retinal vein occlusion (RVO), is a major cause of vision impairment. Many patients experience suboptimal responses to anti-vascular endothelial growth factor (anti-VEGF) monotherapy, necessitating alternative treatment approaches. Faricimab, a bispecific antibody targeting VEGF-A and angiopoietin-2 (Ang-2), introduces a novel dual-mechanism therapy. This study evaluates the short-term real-world efficacy of switching to Faricimab in patients with treatment-resistant ME secondary to RVO. : This retrospective study included patients from LMU University Hospital who were switched to Faricimab due to an inadequate response or adverse events related to prior intravitreal therapy (Ranibizumab, Aflibercept, or Ozurdex). All patients completed a structured loading phase of four monthly injections. Key outcome measures included changes in best-corrected visual acuity (BCVA, logMAR), central subfield thickness (CST, µm), and intraretinal fluid (IRF) presence on optical coherence tomography (OCT). Changes were assessed from baseline (mo0) to three months (mo3). The study included 19 eyes from 19 patients (mean age 63.0 ± 14.2 years). BCVA improved from 0.20 logMAR at baseline to 0.00 logMAR at mo3 ( < 0.01). CST decreased from 325 µm to 280 µm ( < 0.01). The proportion of eyes with IRF reduced from 100% to 32% ( < 0.01). Significant reductions in retinal volume within the 1 mm and 6 mm (both < 0.01) circles of the ETDRS grid were observed. : Switching to Faricimab in patients resulted in significant short-term improvements in BCVA, CST, and IRF resolution. Given the small sample size and retrospective design, these findings should be interpreted as exploratory and hypothesis-generating. Further studies are needed to evaluate long-term efficacy and optimal treatment regimens.
